Alternator failure related to mild hybrid system?

Ok. Thats great then. I just take a look on some paperwork because I’m like the second driver, I’ve got the car from a dealership (not Audi) about 4 months  ago,and there’s lots of paperwork done at Audi by the first driver but nothing about this alternator but I’ve found an offboard diagnostic information system with lots of electrical faults, couple of papers actually ( I think there are all electrics faults of the car) first fault is like battery 48v(a6,c31)- charging fault all of the papers with those electrical faults are from the 3 dec 2024. Now I’m wondering if the dealership bought the car with this alternator issue and they replaced, because if they done that and they didn’t use an genuine Audi/w part I don’t think Audi will replace an aftermarket at no cost but I think the dealership will need to pay for it anyway if not they can get the car back. I’ll find out on Friday when I’m taking the car to Audi.
